化学循环燃烧 (CLC) 是一种很有前途的二氧化碳捕获技术，具有非常低的能源损失和成本。之前的几项研究已经证明了该技术使用气体和固体燃料的可行性。使用 CLC 燃烧生物质将使负二氧化碳排放的概念成为可能。本文介绍了使用松木作为燃料、铁矿石作为氧载体的连续 CLC 装置中生物质燃烧的研究，并分析了影响 CLC 过程的几个参数。使用蒸汽和二氧化碳作为气化剂，在 880-915 摄氏度范围内实现了高碳捕获量 (>95%)。在燃料反应堆出口处检测到焦油化合物。连续运行78 h后，载氧体颗粒的理化性质未发生变化。 (C) 2013 Elsevier Ltd. 保留所有权利。
Chemical looping combustion (CLC) is a promising CO2 capture technology with a very low energy penalty and cost. Several previous studies have demonstrated the feasibility of this technology using both gaseous and solid fuels. The combustion of biomass using CLC would make the concept of negative-CO2 emission possible. This paper presents a study of biomass combustion in a continuous CLC unit using pine wood as fuel and iron ore as an oxygen carrier and analyses several parameters influencing the CLC process. High carbon captures (>95%) were achieved in the interval 880-915 degrees C using both steam and CO2 as gasifying agents. Tar compounds were detected at the fuel reactor outlet. After 78 h of continuous operation, no changes were detected in the physical and chemical properties of the oxygen carrier particles. (C) 2013 Elsevier Ltd. All rights reserved.
